Open source vs Enterprise (Zyvor)
GuestKit (this repo) is the full Apache-2.0 offline disk engine — free for personal, lab, and commercial production use (no license key).
GuestKit Enterprise is Zyvor’s commercial migration control plane — every Command Center screen below — calling the same guestkit doctor evidence. Not a forked binary. Not a feature hostage. Enterprise support, SLAs, and the control plane are licensed separately.

Why teams upgrade
- Spreadsheets stop working for waves and Passports
- Security blocks DIY dashboards — need SSO + audit
- Executives need one readiness number and exportable reports
- Cutover risk is commercial — SLA and workshops
- Engineers keep doctor / vault — Enterprise wraps them in program ops
When to stay on open source
CI / golden-image gates · lab evaluation · small fleets owned by one engineer.
When to contact Zyvor
Hypervisor exit with program governance · regulated SSO/audit · multi-site cutovers · contractual accountability.
